IMPROVEMENT IN OIL-CAN SPOUTS.

Specification forming part of Letters Patent No. 170,718, dated December7, 1875; application filed May 12, 1875.

v usual form.

A staple is firmly secured to the spout at D. To this is attached oneend of a spiral spring, the other end of which is attached to the cap B.This cap, Fig. 3, has the usual filling, a, in the bottom, whichconsists of cork, rubber, or any other suitable material, which, whenthe cap is adjusted on the end of the spout A, makes a tight joint. Thespiral spring 0 is used for the double purpose of holding the cap B onthe end of the spout by its elasticity, and also to prevent the cap frombeing lost when disengaged, as shown in Fig. 2, thereby acting as asubstitute for chains, slots, and other objectional devices.

The spring is made of small brass wire, and coiled to a size which givesmuch elasticity with little power, thereby giving durability, andallowing the ready removal or adjustment of the cap.

I do not claim as my invention the spout A, with a cap, B, and fillinga; nor do I broadly claim the use of springs in connection withspout-valves; but

I do claim- As a substitute for the usual chain and other devices, thespiral spring 0, connected and operated, in combination with the cap Band spout E, as shown and described.
